“…The antibacterial mechanisms [16][17][18][19] may not be creative; however, the emergence of Mg and Ca ions from the waste is significant for sterilization. As can be seen from previous studies, some mineral wastes have been developed for different uses [20][21][22]; however, the activation of the waste at rather high temperature is crucial for obtaining good performance of natural minerals. The current study shows that the processes of milling and subsequent annealing at very low temperatures are sufficient to produce the antibacterial ability of the collected Xiuyan jade waste, which is meaningful for its application.…”

Jade waste is a normal byproduct that makes up much more than the amount of jade extracted. Therefore, recycling jade waste is worth investigating from the point of view of energy conservation. Moreover, it is an environment-friendly material, which is desirable for use in building materials. In this study, Xiuyan jade waste was repurposed as antibacterial additives for building coatings. The powder waste was activated by milling and subsequent annealing. The antibacterial properties of the treated waste were mostly related to the annealing temperatures. Based on the investigations of the phase change and the release of metal ions of a series of samples and their antibacterial activities, the antibacterial mechanism of the treated samples was explored experimentally. The most applicable sample for coatings was finally chosen by considering its pH values and its antibacterial abilities. Antibacterial testing showed that the addition of treated jade waste could enhance the bacterial inhibition rate of building coatings from 60% to 99.9%.

The genus Petrocodon is renowned for its remarkably diverse floral morphology, exhibiting a high level of disparity compared to most genera within Gesneriaceae. In this study, we present a detailed description and illustration of Petrocodon gracilis T. Ding & B. Pan, a new species with unique floral features that is native to Guangxi, China. This species is geographically close to P. jingxiensis H.S. Gao & W.B. Xu and is indistinguishable from P. jingxiensis in vegetative characteristics. However, it can be clearly distinguished from the latter by its shorter pedicels, slender tubular corolla, shorter corolla tube, distinctly unequal corolla lobes with upper ones linear and reflexed and lower ones oblanceolate, and included chiritoid‐like stigma. The presence of linear upper lobes and the chiritoid‐like stigma has not been previously reported in Petrocodon, and the emergence of this new species will further expand the morphospace occupied by this morphologically diverse genus.
